Insulation Overhead Bridge Crane Description:
QY model insulating overhead crane is widely used in electrolyzing of nonferrous metal, aluminum and magnesium metallurgy workshops. Insulation overhead bridge crane is composed of box-type frame, crane travelling mechanism, trolley, electric equipment. In order to prevent the current of electrical equipment would through lifted parts endanger the driver of Insulation overhead bridge crane during working, the insulation equipment is set up at some suitable positions.
It has over three insulation parts to protect the current of electrical equipment from endangering the driver of the crane when working. Insulation overhead bridge crane belongs to heavy working grade, in order to secure safety; main hoist mechanism is matched with double brakes.
Insulation Overhead Bridge Crane Three insulating apparatus:
1.Hook and pulley
2.Lifting system and trolley frame
3.Trolley frame and crane
4.Every insulating apparatus resistance value should be not less than 1MΩ when temperature is 20~25℃ and relative humidity is ≤85%.
Insulation Overhead Bridge Crane Mechanical Parts:
Double welding box girder, beam deflection with DIN/FEM standard
Steel Material: Chinese standard Q235B and Q345B
Trolley rail is made of high strength hot rolled flat steel (16 Mn)
Epoxy zinc-rich painting for one bottoms and two sides of 120μm thick, to achieve a long lifespan, beautiful appearance and good luster
The girder and end beam are connected together by high strength bolts to ensure the structure strength and precision of the whole machine
The end beams are equipped with flat wheel or double rim wheels, anti-friction bearings, buffer blocks and derailment preventing end plate
Maintenance walkway is located on one side of the main girder, consisting of flower pattern plate, 1050meters handrail.
